Outer planets are farther away and made up of gases. Inner planets closer. It's pretty much self explanatory. Hope this helps.
Answer:
h = 6.371 m
Explanation:
Data:
Potential Energy = P.E = 1500 J
Mass = m = 24 Kg
Gravity = g = 9.81 m/sec²
Height = h = ?
Solution:
As the formula for the Potential Energy is;
P.E = mgh
Replacing the values in the above equation
1500 = 24 × 9.81 × h
h = (1500)÷(24 × 9.81)
h = 6.371 m
This statement is true. Organic compounds hold carbon and hydrogen along with oxygen and nitrogen.
Answer:
(a) ![[Y_{p} ]_{max} = \frac{2f}{1+f}](https://tex.z-dn.net/?f=%5BY_%7Bp%7D%20%5D_%7Bmax%7D%20%3D%20%5Cfrac%7B2f%7D%7B1%2Bf%7D)
(b) 
; ![[Y_{p} ]_{max}](https://tex.z-dn.net/?f=%5BY_%7Bp%7D%20%5D_%7Bmax%7D%20)
= 0.026
Explanation:
Since the neutron-to-proton ratio at the time of nucleosynthesis is given:
Therefore:
Then, to determine the maximum ⁴He fraction if all the available 
neutrons bind to all the protons. Since, there are 2 protons and 2 neutrons in a ⁴He nucleus, it shows that there would be 
nuclei of ⁴He.
In addition, a ⁴He nucleus has a mass of 
, where 
is the mass of one proton. Thus, nuclei of such nuclei will have a mass of *.
Assuming that 
, there would be a total of 
protons and neutrons with a total mass of 
.
Thus:
(b) Given:
; τ
= 3*60s = 180 s
![f_{new} = \frac{n_{nf} }{n_{pf} } = \frac{exp (-200/180)}{5 +[1- exp(-200/180)]} =\frac{0.077}{5.923} = 0.013](https://tex.z-dn.net/?f=f_%7Bnew%7D%20%3D%20%5Cfrac%7Bn_%7Bnf%7D%20%7D%7Bn_%7Bpf%7D%20%7D%20%3D%20%5Cfrac%7Bexp%20%28-200%2F180%29%7D%7B5%20%2B%5B1-%20exp%28-200%2F180%29%5D%7D%20%3D%5Cfrac%7B0.077%7D%7B5.923%7D%20%3D%200.013)
= (2*0.013)/(1+0.013) = 0.026
